Central search - Search for all objects

Hello,

we're using central search on SAP CRM 7.0 EhP 1 and when our users want to use it with first entry "All objects" nothing happens? With my user (has SAP_ALL) it works. Also our users don't see the option "Free text" in the different sub menus (like "Accounts", "Opportunitys"....)?

Do we have to assign a certain authority object to our users or do we need to do some additional customizing?

Thanks

Daniel
